Flail Choppers

I plan on purchasing a new flail chopper. I've looked at the New Holland Model 38 Crop Chopper, Deere 972 Flail Chopper and the Hiniker 5710... which is of a very interesting design.   I've pretty well convinced myself that no flail chopper is going to throw forage into the back of a 20' self feeding wagon and certainly not a used Deere 16a or 38 New Holland. The new Model 38 has some improvements in the paddle area which may get more distance... similar to my Fox 844 which is on it's last legs. However anyone out there ever do a recent study of these models and came away with a decision???  Thanks
